What we claim as our invention is 1. In a window control mechanism, the combination with a pivotal window lifter" of a nut swiveled on said arm,

threaded portion engaging said nut, a; swivel mounting providing a journal bearing for said stem, adapting the stemto swing in the plane of said arm, a crank mounted upon said bearing, and gearing carried by said bearing for actuating saidstem from said crank. I, g

2. In a window control mechanism, the combination with a pivotal lifter arm, of a stem extending from said arm having a threaded portion engaged with the arm, a swivel mounting forsaid stem, stem to swing in the plane of said arm, crank journaled in said mounting,

a transvers'ely to ,the stemand gearingcarried by said crank.

, nism for operating said window comprise said mounting for actuating said stem from 3. The combination of a slidable window member, a frame having a chamber receiving said window member in the open position of the latter, and a controlling mcha;

ing a handle mounted'upon the frame near the upper part of the chamber, athreaded stem, a drive connection between said-handle and said threaded stem for rotating the latter upon rotation of the former, said stem projecting downwardly within said chamber, a fixed member within sai chamber" and arranged atone side of said stem, a single contrbl arm having one end fulcrumedon said fixed member and extending across said threaded stem and having itsgopposite end portion in operative engagement with said a window, and a threaded connection between 7 said threaded stem and said control-arm,- said controlling mechanism including two floating connections for permitting said controlv arm to be raised and lowered through movements of thg handle without binding said threaded stem, one of said floating con-v nections being located between the threaded" stemfa'ndthe, controlling arms 4. The combinatiomwitha slidable win-r dow member, of a frame having a chamber receiving said member in its openposition, a control arm for said member arranged within saidv chamber and adapted 'to swmgin a plane substantially parallel to-that of! the window .member, a fulcrum. support for said arm directly engaged bv the arm and stationary within saidhamber, a rotative' threaded stem,- a nut engaging said stemcarried by' the arm," and adapted to rock relative thereto, and means preventing bind I ing pf the stem. due to therelative angular movementofthea'rm. v I i 5. The combination with; a slidable' win-- arm and adapted to rock relative to the tion,

dow member, a frame receiving said member in its open position, a'control arm' for said member fulcrumed at one end within, said chamber to swingiin a plane substantially parallel to the window member and a stem having its fulcrum I end restrained from movement insaid plane transverseto the travel of the window member, a 'rotativethreaded stem, a nut engaging said stem and attached to said arm and adapted to rock relative to thejarm, and means for preventing binding of the stem' the to the relative angular movement of the arm.

6. The combination yvith a slidable window member, a,frame receiving said member in its open position, a' controlarm for said member fulcrumed at one end within said chamber to swing in a plane substan adapting the tially parallel to the window member and having its fulcrum end. restrained from movement in the direction of travel of the window member, a rotative threaded stem," a nut engaging said stem and attached tosaid arm, and means for preventing binding of the stem due to the relative angular movement of the arm. l

7. The combination with'a slidable window member, of a frame havinga chamber receiving said member in its open'position, a control arm for 'Sald member -arranged 7' within said chamber and/adapted to swing in a plane substantially parallel to that of i the window member, a fulcrum support within said chamber for said armydirectly ienga'ged by the arm and restrained from vertical movement, a rotative threaded stem,

a nut engaging saidstem carried by the arm, and adapted to rock relative thereto; and means preventing binding of the stem, due to the relative angular movement of the. arm.

8. The combination with} slidablefwindow member, of a framehaving a chamber receiving said member in its open position, a control arm for said member'- arranged. within said chamber and adapted to swing iiia plane substantially parallel to ,that of the. window member, a .bracket'stationary within said chamber and providing a fixed fulcrumpoirit for the arm,a rotative threaded stem, a nut eng ging said stem carried by the. arm, and a apted to rock relative thereto, and means preventing-binding of :the stem due to the relative angulanmove mentof the arm.

9; The combination with a. slidable win-. dow member, of a frame having a chamberreceivipg', an actuating mechanism for said win"- said members in its open posidow member within, said chamber compris-v I ing a fixed fulcrum support and two-parts, one having the gaging said support and adapted to swing hereupon in a plane substantially parallel A natureof aco'ntrol'arm'enisd travel of the point of receiving said the Window stem, a nut gaging said stem,

tothe window member, and the other being a threaded stem rotatably adapted to actuate said arm, provisionbeing made for a movement of one of said parts in addition to the described movements to permit the necessary application of power from the screw to the arm relative, to said fulcrumsupport.

10'. The combiantion with aslidable window member, of a frame having a chamber member in its open position, a control arm for said member arranged Within said chamber and adapted to swing in a plane substantially parallel to, that of niember, a rotative threaded attached to said. arm and enand actuating means for said stem, provision being made for sWing-" ing of said stem in substantially the plane of the arm to prevent binding of the stem. 11. The combination of a slidable window, a frame having a chamber receiving said window in the open position of the latter, a control mechanism for operating said window comprising a rotating handle, a threaded stem projecting within said chamber, a connection between said stem and said handle for efl'ecting a rotation of the former upon the rotation of the latter, a single arm member arranged within said chamber, a nut earned by the arm member and, movable in relation thereto, said nut engaging said stem member, a mounting fixed in relation to the frame and to which the arm member is directly connected, whereby upon raising and lowering of said arm member the latter will be caused to rock in a plane substantially parallel tothe window member, and a mounting for the stem member fixed in relation to the chamber, the connection between one of its mounting permitting movement of such member 'n vent bin ing of said control mechanism.
